Answer:
Counselor's estimate isn't correct.
Step-by-step explanation:
Total number of students in university = 30,600
2% break 3 of the languages
Therefore, 2/100 × 30600 = 612 students break 3 of the languages in the University according to the counselor.
In a random sample of 240 students, 20 break 3 of the languages.
% = 20/240 × 100 = 8.33%
SinceTotal number of students = 30,600
Therefore, 30,600/240 = 127.5
Which means 127.5 × 20 = 2550.
Which means 2550 students break 3 of the languages as against the 612 students stated by the counselor.
Answer:
$280
Step-by-step explanation:
if you do 2.00+1.50 you get 3.50. Then you do 3.50 ×80 you get 280 dollars
Although the student in the example used in this question did not make
too many errors, there is a better way of working out this equation so
that you will find the correct answer. In an equation like this where
you need to get I on it's own, you need to divide everything by two to
get -w+P over 2 = l. To get to this point, to start with you would need
to do -2w+P=2l instead of P-2w=2l.
Answer:
f^-1(x) = (-1/5)x - 11/5
Step-by-step explanation:
f^-1(x) is the inverse so it must be
f^-1(x) = (-1/5)x - 11/5
